MIPI 2022 Challenge on Under-Display Camera Image Restoration: Methods and Results
This work tackles the problem of improving image quality for under-display cameras in mobile devices, but it is incremental as it builds on existing challenge frameworks and datasets.
The paper introduced the MIPI 2022 Challenge to address the lack of high-quality data and collaboration in mobile intelligent photography, specifically focusing on Under-Display Camera Image Restoration, where 19 teams submitted solutions that achieved state-of-the-art performance.
Developing and integrating advanced image sensors with novel algorithms in camera systems are prevalent with the increasing demand for computational photography and imaging on mobile platforms. However, the lack of high-quality data for research and the rare opportunity for in-depth exchange of views from industry and academia constrain the development of mobile intelligent photography and imaging (MIPI). To bridge the gap, we introduce the first MIPI challenge including five tracks focusing on novel image sensors and imaging algorithms. In this paper, we summarize and review the Under-Display Camera (UDC) Image Restoration track on MIPI 2022. In total, 167 participants were successfully registered, and 19 teams submitted results in the final testing phase. The developed solutions in this challenge achieved state-of-the-art performance on Under-Display Camera Image Restoration. A detailed description of all models developed in this challenge is provided in this paper.
